BEFRIGERATOR CONSTRUCTION.

Application led July 31, 1925. Serial No. 47,297.

The present invention relates to refrigerator construction and more particularly to means for finishing the doors and frames of refrigerators and providing sealing means l therefor.

Among the objects of the invention to provide a simple, cheap, efficient and ornamental finish for door edges and frames and a finish that is easily and quickly applied.

Another object is an efficient air-tight seal for such doors.

Y Still other objects will be readily apparentto those skilled in the art upon reference to the following description and drawing,v in which- The figure is asection through a part of a refrigerator wall vand the adjacent edge portion of a door therefor..

In the drawing there is shown a section of a refrigerator wall at 1 and of the edge of a refrigerator door at 2. The. interior of these parts is of the -usual construction,

that is, they consist of awooden outer wallportion 3 with anadjacent heat insulating layer of corkboard-/t having a sheet 5 of metal or other suitable material on each side thereof. In addition, the wall section is provided with an inside wood layer 6.

As is well known in refrigerator construction, these parts may be covered with formed metal sheathing7 which itself" is covered vwith a thick layer of vitreous enamel.

The metal sheathing is'first formed of the proper size and shape and the enamel applied in a process requiringa high heat. This operation frequently causes the metal to become somewhat distorted and to vary from the intended dimensions. Consequently, it is diiiicult to prepare such sheathing so thatl the edges will lie in the same relative position on two like bodies.

. This objectionis overcome in the present Structure by using finishing strips which overlap the edges of the sheathing and are secured thereto and to the body.

Such strips are preferably ofaluminum and are indicated at 8, 9 and 10. The 'strip 8 is secured at the edge ofthe door and extends from over the edge of sheathing 7 to somewhat beyond the edge of thedoor. The strip 9 overlies the edge of the inside sheathing'7 of the wall and extendsabout half the adjacent edges of strips 9 and 10 a packin@ strip which consists of a tubular part12 having a longitudinal flange 13. The iange is inserted under the edge of strip 10 and secured therewith to the body by any suitable means, such as by tacks or screws. The

tubular portion may be hollow but is preferably filled with a rubber strand cord, the outer cover being preferably also of rubber. y When the door is shut the packing strip will be compressed between the step 14 and the corresponding step 15 on the door and make an airtight seal for the latter, it being understood that the construction shown extends entirely around the door opening..

The edge of inside sheathing 7 on the door is preferably flanged asr shown at 16 and is secured by finishing strips of molding 17, the latter being secured by screws or nails, not shown.

Having, now described the invention and the preferred form of embodiment thereof, it is to be understood that the said inven- `tion is not to be limited to the precise details asshown` and described but only bythe i scope of the claims which follow.

1. In refrigerator construction, a heat insulated wall body having a stepped door Opening, said body, metal sheathing on the outside of said body, the inside and outside sheathing having adjacent edges spaced apart, and finishing strips consisting of two adjoining strips of metal overlying said edges and covering the body therebetween, the adjoin ing edges of saidistrips lying on a step of said dooropening, and a door gasket secured to said step longitudinal of said junction.

2. In refrigerator construction, a heat insulated wall body .heling 'a stepped doormetal sheathing on the inside of" opening, metal sheathing said body, metal sheathing on the outside ofsaid body, the inside and outside sheathing having adjacent edges spaced apart2 and finishing strips consisting of two adjoining' strips of metal overlying said edges'and covering the body therebetween, the adjolnon the inside of cured under one of said stri s.
